MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 790,442, dated May 23, 1905.

Application iiled September 8, 1904. Serial No. 223,742. l

even when the number of pupils is larg'e to bring' the subject ot' instruction simultaneously and continuously to the eyes and ears of all the pupils, so that the fundamental ideas-otl instruction in music and singing can be just as easily impressed in class teaching' as has been possible hitherto with individual teaching'.

the position ot' a note and the construction ot' the dii'l'erent scales are most easily understood itl when a note is sounded the position o'tl such note in relation to the other notes belonging' to a scale is simultaneously indicated by means of the keyboard. lV ith the means at present available such a method ot' instruction is only possible with individual teaching, but in class teaching' the teacher is only able to avail himsel'tl oi' the scales.

In order that general-that is to say, class-- teaching may be carried on in the same manner as individual teaching', the keyed instrument which forms the su bject ot' this invention is so constructed that it can be suspended with the keys vertical and be played in that position, so that all the pupils are able to follow the remarks of the teacher, the teacher being further enabled when playing the instrument to keep the class in view.

Figure l oi' the accompanying' drawing's is a diagram showing' the instrument hung' on a blackboard, and Fig. 2 is a transverse section of the instrument on a larger scale.

In the case a the ordinary foot is replaced by suspension-hooks L, which, as shown in the drawings, are preferably attached to arms d,

In connection herewith it is recognized that collapsibl y supported on the casing a by means ot' hing'es g, so that the instrument can be hung on the blackboard in the class-room and the keys be conveniently reached. IV hen the instrument is hung up, the foot-lever /i is connected throug'h the strap Il', which can be lengthened or shortened by means oi'I a buckle, according' to the height at which the blackboard is suspended, with the rod y), which eng'ages with the angle-lever s, seated in the block in, and connected with the bellows if.

In order that it may be possible to play the instrument like any other harmonium, even when it is laid on the table, the rotary axis of the lever s is connected outside the front ot' the casing with a lever-arm a. lVhen the instrument is played in a horizontal position, the `toot-lever /L is connected with the lever n.

It' the suspended instrument be iittcd .with strings or wires which are struck, the levers s and n and the foot-lever /t are ot' course omitted.

In the support situated above the keyboard a sheet ot' music is arranged. for the purpose of enabling' the exercises with the keys to be immediately repeated with the notes.

That I claim, and desire to secure by Letters Patent, is-

l. A musical instrument for use in musicand singing' lessons, provided with a keyboard, and means for suspending' the instrument with the keys vertical substantially as and for the purpose described.

2. Am usical wind instrument provided with a keyboard, a bellows within the instrument, a pivoted angle-lever connected at one end to the bellows, means for detachably connecting' a `foot-lever or treadle with the angle-lever in such manner that the bellows can be actuated when the keyboard is in a vertical or horizontal position and means for suspending the instrument with the keys vertical substantially as described.

In testimony whereof I have aflixed my signature in presence of two witnesses.
